Gigabyte Ghost GM-M8000X Mouse

"While optical mice have finally managed to vanquish ball mice as the standard pointing device, a lot of computer users have been content that their optical mice are "good enough". Gamers on the other hand demand way more from their mice, and that's why a little beauty by the name of the Gigabyte Ghost GM-M8000X laser gaming Mouse exists. You'll find a nine button performance mouse built for competitive gaming around a 6000 DPI laser sensor with on-the-fly sensitivity adjustment and a high 1000 reports/second USB polling rate."
